' sum u [1F 4 mvsmon ERNEST C. WRIGHT FIG. /2 BY ATTORNEY SHIPPING AND DELIVERY SHELVED CONTAINERS FOR FOOD This invention relates to shipping and delivery containers equipped with shelving.

In many delivery services for pies, cakes, prepared food trays, and similar items, wherein the same must be individually supported on shelves, metal containers having shelves are used. Such containers are heavy, costly, and must be returned to the shipper when empty.

An object of this invention is to provide a shelved container made of paperboard, or like inexpensive material, which may be easily erected from prepared flat blanks.

Another object is to provide a shelved container provided with handle means for transporting and delivering prepared food trays from kitchens to aircraft or to other desired places. The prepared trays are individually supported on shelves, since they cannot be stacked. I

Another object is to provide a shelved container which is light in weight, inexpensive, and may be considered to be disposable.

Further objects and advantages will be apparent from the following description and accompanying drawings, wherein:

FIG. 1 is a plan view of the flat blank from which the carton is erected;

FIG. 2 illustrates the side rails of the shelving assembly;

FIG. 3 is a plan view of the flat blank from which the shelve ing is erected; I

FIG. I is similar to FIG. but shows the front closure panels in closed position;

FIG. II is similar to FIG. 7, but shows the rear closure panels in closed position;

FIG. I2 is similar to FIG. 10, but shows the front closure open and exposes the front of the shelving assembly; and,

FIG. 13 is a fragmentary sectional view on line 13-l3 of FIG. l0, showing the interlocking relation between the tab and its cooperating slots.

Referring to FIG. I, blank A comprises a flat sheet of suitable material, such as corrugated board of suitable strength. The flat sheet is prescored to present a pattern of score and fold lines, and is die-cut and punched to the configuration illustrated in FIG. I. Transverse score lines I, 2 and 3 define bottom panel 5, side panel 6, top panel 7 and side panel 8. Horizontal score lines 9 and I0 define end flaps II and I2 at opposite edges of bottom 5, closure panels l4 and I5 at opposite edges of side 6, flaps l6 and 17 at opposite edges of top 7, and closure panels l8 and I9 at opposite edges of side 8.

Closure panel I4 is provided with a locking tab 21 which is inserted into locking slot 22 of closure panel l8 when the blank is erected to form a carton for the shelved container. Closure panel I5 is provided with a partly punched out slot 23 having an infolding flap 24. Closure panel I5 is further provided with a locking flap 25 having several score lines. As will be described herebelow, flap 25 cooperates with slots 26 and 27 formed in closure panel l9 for interlocking the two closure panels in closed position. A punched out portion 29 at the edge of closure I9 is complementary to the end configuration of slot 23 when the carton is erected and the closure panels are in closed position, as illustrated in FIG. l0.

The shelving assembly comprises two sides 30 and 3!, illustrated in FIG. 2. Each side is a rectangular sheet of suitable material. Preferably, the material is paperboard of suitable rigidity and strength for the desired load.

The several shelves are formed of flat blanks, each properly scored and die cut to the configuration illustrated in FIG. 3.

Each blank B has score lines 33, 34, 35 and 36 which divide the blank into shelf portions 37 and 38, a side 39 and two end flaps 40 and 4l, which flaps, when folded at right angles to the shelf portions 37 and 38, provide a side means opposite to side 39. Blank B is provided with front cutout portions 42 along one edge thereof and rear cutout portions 43 along the op,- posite edge thereof. Cutout 42 allows access to the contents and cutout 43 provides space for dry ice or other coolant.

A blank B is folded along its fold lines to form or erect an open-ended boxlike structure, illustrated in FIG. 4. Thus, the top of the box forms shelf 37 and the bottom of the box forms shelf 38. The desired number of erected boxes are secured to sides 30 and 31 at spaced distances, as illustrated in FIG. 4, to present the desired number of shelves 37 and 38. As shown in the figure, the erected boxes are spaced from each other so that a shelf 37 is below a shelf 38 to provide a space for the articles supported by a shelf 37. The erected boxes may be secured to sides 30 and 3l by any well-known means, such as by utilizing a suitable adhesive or by stapling.

The assembled shelving structure of FIG. 4 may be collapsed or compacted for shipping or storage. In view of fold lines 33 to 36, inward pressure on sides 30 and 3l will cause the individual shelf structures 37 to 41 to collapse, the several parts hinging along the fold lines. Thus, a compact package is formed with sides 30 and 3| close together and the folded shelves therebetween. I

The container is erected from blank A by folding sides 6 and 8 along fold lines 2 and 3 and folding bottom panel 5 along fold line I to form a rectangular box. Bottom 5 is connected to the lower edge of side 8 by any desired means. Preferably, the connecting means comprises an adhesive tape means located on the outside of the box formation and affixed to the adjacent edges of bottom 5 and side 8. FIGS. 5 and 6 illustrate the erected box formation comprising top 7, sides 6 and 8, bottom 5 and closure panels l4 and I8 and I5 and I9. For explanatory purposes only, the closure means comprising panels l4 and 18 may be considered the rear closure, and the closure means comprising panels l5 and 19 may be considered the front closure of the container. The front closure is the one which is opened to gain access to the interior of the container and its contents supported by the shelves.

The erected box is closed at its rear by folding top tab l6 and bottom tab ll inwardly, and thereafter folding in panels l8 and 14, with tab 2] being inserted in slot 22 to maintain the closure panels in their closed position, as illustrated in FIG. ll. Top flap I6 is provided with fold lines 50 and SI, whereby fold line 50 can act as a hinge for raising flap 16 from a closed position to an open position, whereby the interior of the container may be inspected without opening panels 14 and I8 and will allow 1 for the insertion of dry ice or other coolant. Flap I6 is provided with a hinged tab 32 which provides a vent opening in and a finger grip for flap l6.

After the rear of the box is closed, as illustrated in FIG. ll, the shelving illustrated in FIG. 4 is inserted into the front of the box, as illustrated in FIG. l2. The contents to be transported and delivered in the unit, such as trays with prepared meals, pies, display merchandise, or similar articles which require individual shelf support, are placed on the shelves 37 and 38.

The box is then closed at its front by folding end flaps l2 and I7 inwardly and thereafter folding panel l5 to close the front opening and folding panel l9 thereon. The folded panels l5 and 19 are locked together ,by inserting tab 25 into slots 27 and 26. As illustrated in FIGS. l0 and 13, tab 25 is inserted into slot 27 as panel I9 is folded over panel l5. Tab 25 is scored along lines 46, 47 and 48, as illustrated in FIGS. l and 13. Thus, Portions of tab 25 can be folded along fold lines 46, 47 and 48 and the end of the tab inserted into slot 26 of panel l9. Thus, tab 25 is folded to assume a Urshape, with the legs of the U passing through slots 26 and 27, whereby a strong interlocking joint between panels l5 and I9 is formed. The joint is easily unlocked by pulling the end of tab 25 out of slot 26, straightening out the tab to generally align it with slot 27, and then pulling panel l9 to disengage slot 27 fromthe tab. it will be understood that a single panel may be used in place of the two closure panels in either the front or rear of the carton and that other locking means may be employed for either the doubleor single-closure panels The container is further provided with handle means for carrying it when loaded. As illustrated in FIGS. land 8, top 7 is provided with slots 55. A handle 56, made of plastic or similar material, is provided with end lugs 57 connected by neck portions 58 to the body of the handle. There is sufficient flexibility and resiliency in the handle structure 5658 to permit insertion of lugs 57 in slots 55, with the final positioning of the lugs into the locking position illustrated in FIG. 8.

A combined vent and hand hold comprising slot 23 and hinged tab 24 is provided in closure panel 15. Slot 23 provides an opening for insertion of fingers to facilitate the manipulation of the container in assembly, storage, stacking, or removing the container from the galley.

Although the invention has been disclosed in a preferred embodiment for purpose of illustration, it will be evident that various changes and modifications may be made therein without departing from the scope and spirit of the invention.
